Application e August 7, 1911.

To all 'who/m muy concern.'

Be it known that we, CARL H. Bissen, and ARTI-inn E. View, citizens oit the United States, of Syracuse in the county of Onondaga and State of New York, have invented a. certain new and useful Signal- Lamp, of which the tollmying is :i specification.

(')ur invention has for its object the pro` duction of signal lamp and particularly to constructions by which the lens or globe is supported and by which the lamp within the lens or globe can be removed without disturbing,` 'the lens; and it consists in the combinations and constructions hereinafter set forth and claimed.

lin describing' this invention reference is had to tbe accompanying drawing in which like characters designato corrcspfmdingv parts in all the views,

Figure i. an elevation partly in section of a preferable form of this signal lamp. Fig. 2 is an inverted View ot' parts seen in Fig'. l.

qThis lamp comprises, generally, a cap, a base, :1 Cylindrical signal lens interposed between the cap and the base, and means for clamping the cap and the base toward each other and thereby holding the lens in position.

l is the cap vraie-h' maybe of any desirable form size and construction and is 'nere shown as provided with an `interzral-ly threaded nipple 2 by which a conduit il 'for inolosing electric wires, is attached to the cap. The cap may also be provided with a suitable incandescent electric lamp socket et for supporting an incandescent electric lamp 5 as indicated in dotted lines.

6 and 7 are respectively sections of the base, and 8 is the lens interposed between the cap and the base, the cap being provided with a seat 9 for the upper edge of 'the lens 8 and one of the sections as the section 6 of the base being also provided with a seat l0 for the lower edge of the lens, suitable packing rings l] beingr interposed between the upper and lowe: edges of the lens and the seats 9, l0.

The section 6 of the base is here shown as in the form of e ring having a flange 1Q on its upper face extending into the lens and llaa/ing an annular groove 13 on its lower face.

Specification o Serial No. 642,779.

The section 7 is discoidal in forni and serves as a bottom for the lamp, and bears i gainst the ring G. Said section 7 is :formed with an upwardly extending annular flange lei. for entering the groove i3 and bearing against the bottom thereof.

The means for clann'iing the base and cap toward each other comprises parts for clmnping` the cap and the section 6 of the base, and parts 1for clamping the cap and the section 7 oi' tbe'base. .its here shown the clamping means comprises rods 15 located dianietrically opposite each other and pivotod at their upper ends at i8 to the cap and having their lower ends threaded and movable tl'ironlli the open ends of external, di a mctrically disposed slots 'li' in ('utwurdly projecting' ears 'i8 on tbe 'ingr (l, and nuts 19 turiiing' on the threaded ends of the rods against the. under faces of such ears 18; and snrii clamping means also includes additional rods 2O similar to the rods 15 and pivood et Q1 at their upper ends to the cap and haring their lower ends threaded and morable through diametrically disposed open ended external slots 942 provided in ears 23 on the section 7, and nuts 24 screwing on tho threaded ends of said rods 20 against the under 'tacos of the ears Q2. The ears 23 are located substantially midway between the ears i8.

Owing to the arrangement of the clampingif sections (l and '7 with respect to the lens d, the section 7 oi the base can be readily removed to replace a burned out incandes-v cent lampvithout removing the lens, and when desirable the lens can be readily re moved.

That We claim is:

l. A lamp comprising a cap, a base., a hol` low body interposed between the cap and the base. the base comprising upper and lowerl sections, one bearingr against the body ani t'ne other against the section wl1icl=bcars against the body, means for clamping the upper section against the body and coacting therewith at opposite points on the section.y and means for clamping the lower section against the upper, the last-mentioned means coaoting with its lower section atpoiiits between the points of eneainmrnt of1 tlie` first clamping means and the upper section, substantially as and for the purpose described.
